Faster Top-Entry Model Among 19 Robots in Orlando

Sepro Group is introducing the newest S5-25 Speed top-entry robot at NPE2024, targeting fast-cycling injection molding applications. Upgrading to a more powerful servo motor and gear box on the horizontal (X) axis has resulted in 63% quicker acceleration and faster overall cycle times, as just some of the design improvements made since the robot’s introduction in 2018 at Fakuma. The top-entry configuration results in a smaller molding cell footprint compared to side-entry robots often used in high-speed applications. Sepro says ideal applications include simple packaging like flowerpots and thin-wall food containers and tubs.  

Now equipped with Sepro’s ECO Air feature, the S5-25 Speed has reduced compressed-air requirements for vacuum part gripping by as much as 85%. Instead of continuously using compressed air, the ECO Air system now monitors vacuum levels and only initiates vacuum generation when it’s required.  

In one of three demonstration cells in the Sepro booth, the S5-25 Speed is paired with a 5X-25 robot to compare performance in side-by-side tests of speed and agility. Both units are based on the same mechanical platform but, while the S5-25 Speed is built for fast acceleration and short cycles, the 5X-25 is a 5-axis servo configuration with a 2-axis servo wrist, helping it excel at complex and precision part manipulation.

Another cell in the Sepro booth features three robots supporting a 125-ton Milacron Q Series injection molding machine. A Success 11X 5-axis Cartesian robot, a 6-axis 6X-170 articulated-arm unit and a cobot will handle not only part removal but also degating, laser marking, sorting (using 2D and 3D vision), label application and packing. All operations will be integrated by a Sepro Visual 3 control system.

The third demonstration in its booth features a 7X-55 robot designed to service larger molding machines up 2,500 tons. Here the robot will handle four different big parts: a rollout garbage can, a large-diameter pipe fitting, an automotive component and a heavy dumbbell. Quick-change end-of-arm tooling (EOAT) enables the robot to handle each part in succession, demonstrating how automation can support efficient short-run production of large components.

In addition to the six Sepro robots in its booth, a further 13 are operating on the stands of partner exhibitors, so that 19 Sepro robots in all will be running in Orlando, making Sepro’s NPE2024 presence its largest ever in terms of individual robots it has exhibited at a trade show.

Milacron is showing four private-labeled robots supplied by Sepro: a Success 33, two 6-axis articulated arm units will operate together in a Sepro-automated cell, and an S5-15 will operate on another Milacron machine. A fifth Milacron/Sepro robot, a servo-driven S5 Picker, can be seen on a Milacron press demonstrating gas-assist molding at the Bauer Compressors booth. Sepro will also supply end-of-arm tooling and guarding for all these installations.

Maruka is operating a total of four Sepro robots, with Cartesian units including a 5-axis 5X-15, a Success 11 and a Success 22, and a 6-axis articulated-arm 6X-70 also exhibited.

Elsewhere, Shibaura is operating a 5X-25 in axial configuration for clamp-end part deposition with Sepro-provided EOAT; Chen Hsong has a 5X-35 on a 700-ton press; and hot-runner system supplier Incoe is demonstrating a Success 11X on a 240-ton LS Mtron machine, with Sepro-provided conveyor and guarding.
